Chairman Dr. Hideaki Watanabe

Contribute to strengthening our nation's defense technology capabilities

  The Defense Technology Foundation (DTF) has published the Defense Technology Journal, a monthly information magazine on defense technology, which is subscribed to by the Ministry of Defense, other relevant ministries and agencies, defense-related companies, and many people interested in defense technology. In addition, DTF has 6 technical fields of research subcommittees to exchange information among member companies, conduct surveys of technological trends overseas, and hold technical reports. Furthermore, DTF gives the Defense Technology Seminar to which expert speakers were invited. Along with the research, studies, and services DTF has provided to the Ministry of Defense and the Ministry of Economy, Trade and Industry, DTF will also assist the defense community in addressing the shortage of highly skilled personnel to handle a diverse and expanding workforce.

  In February 2022, the Russian invasion of Ukraine prompted Japan, along with several other countries around the world, to reinforce its defense efforts. By the end of 2022, the National Security Council and the Ministry of Defense had reviewed three security-related documents of the country. In these documents, it has been emphasized that strengthening the defense technology base and the accompanying public-private partnerships are crucial. In June 2023, the Ministry of Defense issued the Defense Technology Guidelines, which outline the technologies that the Ministry will prioritize in the future. DTF will work to improve Japan's defense technology capabilities in alignment with these timely and important guidelines.
